PRINTING ATTACHMENT lFOR ROLLPAPER HOLDERS.

SPECIFICATION forming part of Letters Patent No. 579,549, dated March 23, 1897.

Application filed December 29, 1896. Serial'No. 617,387. (No model.)

Z'o @ZZ whom, it' may concern..-

Be it known that I, VILLIAM B. RUST, a citizen of the United States, and a resident of Portland, county of Multnomah, State of Oregon, have invented a new and useful Improvement in Printing Attachments for Roll-Paper Holders, of which the following is a specification,reference being had to the accom pan yin g drawings as constituting a part hereof.

My invention relates to devices designed to print on the wrapping-paper wound on the well-known rotary holders; and the ob ject of my invention is to introduce certain improvements fer the purpose of perfecting such device, as will be apparent from the description of my invention herein given.

Figure 1 in the drawings is a vertical section `taken through the center of my invention.

Fig. 2 is an end elevation thereof. Fig. 3 is a partial elevation taken from the back of my invention with parts broken away, so as to disclose as much of the construction thereof as possible. Fig. 4 is a perspective of a detail, and Fig. 5 is likewise a detail.

The numbers designate the parts referred to.

My invention is mounted on two horizontal slats 1 1, arranged oppositely and to be secured on the table on which my invention is to be placed by means of ordinary wood or thumb screws 2 3, as shown. The slats lare respectively provided with the horizontal slots 4 and the slanting slots 5, (i, and 7.

The printing mechanism is contained in the case 8, which is mounted on said slats 1 1'by means of .the wire frame 9, the members ol' said frame W91 having at their ends eyes 6C, through which are inserted the ends of the rod 10, extending between and through the slots 4 of t-he slats 1 1, the ends of the rod 10 being provided with a screw or other device adapted to prevent the same from being pulled out of such slots 4.

The coils 11 around the end ofthe rod 12 form a hinge, and the upwardly-projecting part of the'frame 9 extends around the front of the case S and is affixed thereto by crimping the edges of the case over the wire and xin g the parts so united by soldering. y

The rod 12 may be shifted laterally from one to either of the other slots 5 6 7 to adjust the printing-roll to the face of the wrappingpaper as the diameter of the latter diminishes by consumption. The ends 9 and 9b, as is apparent, slide with the rod 10 in adjusting the positionof the rod 12.

The prin ting-roll 13, bearing against vthe face of the paper roll P, the inking-rolls 14 l5, and the blotting-roll 16 are arranged in the case S and cooperate together, as shown in Fig. 1. The bearings Vfor the rolls 13 and 16 are fixed.'

The inking-rolls 14 and 15 are journaled in slotted bearings 17 and 18, (see Fig. 2,) so that by means of the coil-spring 19 they will .automatically adjust themselves to the surface of the printing-roll, said slotted bearings giving to the in king-rolls some play to allow for any unevenness of the surface of the printing-roll.

The inking-rolls (see Fig. 5) have a covering of some ink-retaining material and are respectively provided with the longitudinal slots 20 21 22 23, filled with some absorbent material for retaining an additional supply of ink, to be diffused to the surface-covering of such rolls as the ink on the latter is used up, and the vertical peripheral slots 24 25, with which theinking-rolls are respectively provided, are designed to receive and hold any ink drainage from the surface of such rolls. The roll 16 is also covered with some absorbent material and is interposed between the upper inkingroll and paper surface to assist in evenly distributing and removing any superfluous ink on the face of the printing-roll.

My invention is applied to thepaper-holder in the usual way, being fixed between the standards of the latter, and the frame 9 is made of spring-wire and adapted to press the printing-roll against the paper roll.

New what l claim is- 1. 1n a roll-pape1'printin g attachment in combination the frame 9 and connecting-rods 10, 12, mounted upon a suitable support adapted to be affixed to a table or other surface, and to admit of the frame being laterally shifted thereon to adjust the device to the face of the paper roll, the case 8 and the printl ing mechanism mounted therein and comprising the printing-roll 13 the inking-rolls 14 15, and the blotting-roll 16, the bearings for the rolls, 13, 16, being fixed and the rolls 14 and 15 being journaledv in slotted bearings, and adapted to bear against the surface of said printing-roll, substantially as described.

IOO

2. In a roll-paper-printing attachment in combination the frame 9 and Connecting-rods lO 12, mounted upon the slats 1, and 1, the oase 8 containing the rolls 13 14 15 16, the slotted bearings 17, 18, for the rolls 14 15, and the spring-s 19 for the purpose specified, the hiking-rolls, 14, 15, having longitudinal and peripheral slots 20, to 23, and 24, 25, the fornier containing' some absorbent material, substantially as set forth. ro

In Witness whereof 'I have hereunto affixed my signature in the presence of two Witnesses.
